Why my duncan is not opening?

[endlessrealm]

My phosphate is 0.09, nitrate is 8.6. Im using g5 radion at 65%. Ab+. When the lights are on my duncan closes itself. Im confused. Is that means too much light? The coral is 5 days old

They do best under moderate light and water flow
Too much light and they expel zooxanthellae and too little- they shrivel
Assure salinity and nitrate not elevated and feed it mysis shrimp occasionally

Shrimp annoy many LPS.
